Best puke-inducing workout: James Dorris at The Edge

Amateur boxing champ James Dorris isn't done punishing folks. But the 37-year-old isn't doing it with the leather gloves that earned him belts from the International Amateur Boxing Association in 2010 and 2011. Instead, Dorris carves people into mean slabs of muscle by running a “warrior training” boot camp in the foothills where he grew up. Combining his boxing and mixed-martial arts workouts with the training he undergoes as a Folsom Police Department officer, Dorris makes sure the clients who take his classes at The Edge in Martell leave hurting. In a good way. “My philosophy is to train people as if they're training for a fight,” he said. Dorris built his following by making sure each session is different from the last. Clients, he promises, “will never see the same workout.” They will, however, see gains with the pain. (916) 220-9211, www.theedgestrengthand training.com.
